Abstract

Dispersion relations are derived for longitudinal waves in a relativistic plasma with an arbitrary anisotropic particle distribution function. Longitudinal waves with phase velocity lower than the speed of light are shown to exist in such a plasma. The damping rate of longitudinal waves due to the Cerenkov interaction with plasma particles is derived for such a plasma. The instability of a beam of high-energy particles in such a plasma is studied. As the anisotropy of an ultrarelativistic plasma becomes less pronounced, the maximum hydrodynamic growth rate decreases.

Longitudinal waves and two-stream instability in a relativistic plasma

Journal Article Lominadze, D G ; Mikhailovskii, A B - Sov. Phys. - JETP (Engl. Transl.); (United States)

We investigate the problem of longitudinal waves in a relativistic plasma, with phase velocity lower than the velocity of light. We show that such waves exist at arbitrary particle momentum distribution function that falls off rapidly enough at large momenta. Earlier papers dealing with these questions are analyzed in connection with the problem of pulsar radiation, and the causes of the unclear and confused views advanced in some of these papers are discussed. Relativistic-plasma instabilities due to Cerenkov buildup of longitudinal waves by beams of high-energy and low-energy particles are investigated.

Covariant kinetic dispersion theory of linear waves in anisotropic plasmas. I. General dispersion relations, bi-Maxwellian distributions and nonrelativistic limits

Journal Article Schlickeiser, R - Physics of Plasmas

The properties of longitudinal and transverse oscillations in unmagnetized anisotropic plasmas of arbitrary composition are investigated on the basis of Maxwell equations and the relativistic Vlasov equation. The longitudinal and transverse dispersion relations for plasmas with arbitrary distribution functions are derived. These dispersion relations describe the linear response of the system to the initial perturbations and thus define all existing linear plasma modes in the system. By analytic continuation the dispersion relations in the whole complex frequency plane are constructed. The further analysis is restricted to the important case of anisotropic bi-Maxwellian equilibrium plasma distribution functions. Explicit forms of themore »« less

Electrostatic waves in a relativistic and anisotropic plasma stream electron waves and ion-acoustic mode: Fusion instability

Journal Article Mohanty, J N - Phys. Rev. A; (United States)

The electrostatic dispersion and instabilities for an anisotropic relativistic plasma stream are analytically studied for various regimes with streaming dissipation relevant to the analysis of fusion and turbulence in beam-plasma and wave-plasma interaction. It reveals the modified spectrum of streaming dispersion and onset of instability at nonrelativistic temperatures suitable for space, at moderately relativistic temperature including fusion, and at ultrarelativistic temperature limit relevant to astrophysical plasmas and pulsars.

Plasma waves in a relativistic, strongly anisotropic plasma propagated along a strong magnetic field

Technical Report Onishchenko, O G

The dispersion properties of plasma waves in a relativistic homogeneous plasma propagated along a strong magnetic field are studied. It is shown that the non-damping plasma waves exist in the frequency range omega sub p or omega or omega sub L. The values of omega sub p and omega sub L are calculated for an arbitrary homogeneous relativistic function of the particle distribution. In the case of a power ultrarelativistic distribution, it is shown that, if the ultrarelativistic tail of the distribution drops very rapidly, slightly damping plasma waves are possible with the phase velocity.
Nonresonant kinetic instabilities of a relativistic plasma in a uniform magnetic field: Longitudinal and transverse mode coupling effects

Journal Article Tautz, R C ; Schlickeiser, R ; Lerche, I ; ... - Journal of Mathematical Physics

The stability properties of relativistic plasmas embedded in a uniform magnetic field are investigated for longitudinal and transverse modes and with coupling effects between these modes. The direction of wave propagation in the plasma is not necessarily either parallel or transverse to the ambient magnetic field. The basic dispersion relation equations are given for arbitrary propagation directions. Detailed examination is focused on perpendicular wave propagation in this paper. The concept of neutral points in wave number space, introduced by Harris [Phys. Rev. Lett. 2, 34 (1959)], is generalized to allow for the inclusion of ion effects and the effects ofmore »« less
